Loot system 의 modern ARPG influence. 2. Skill tree 의 RPG genre 의 standard. 3. Online economy 의 trading mechanics. 4. Modding scene (Median XL, Path of Diablo). ## 💻 패턴 ### Pattern 1 — Loot table weighting (pseudocode → C) ```c typedef struct { ItemType type; int weight; } LootEntry; LootEntry table[] = { {NORMAL, 60}, {MAGIC, 25}, {RARE, 10}, {SET, 3}, {UNIQUE, 2} }; int roll = rand() % 100; int acc = 0; for (int i = 0; i < 5; i++) { acc += table[i].weight; if (roll < acc) return table[i].type; } ``` ### Pattern 2 — Magic find (MF) calculation ```c // effective_chance = base_chance * (1 + MF/100) // but with diminishing returns formula float effective_mf(float mf, float factor) { return (mf * factor) / (mf + factor); } // Unique factor = 250, Set = 500, Rare = 600 ``` ### Pattern 3 — Skill synergy (D2 LoD) ```c // Damage = base * (1 + 0.10 * synergy_skill_level) int fireball_damage(int level, int fire_bolt_lvl, int meteor_lvl) { int base = 18 + level * 4; float synergy = 1.0f + 0.10f * (fire_bolt_lvl + meteor_lvl); return (int)(base * synergy); } ``` ### Pattern 4 — Item affix prefix/suffix ```c struct Item { BaseType base; Affix prefix[3]; // e.g., "of Speed" Affix suffix[3]; // e.g., "Cruel" int sockets; }; // Rare = 4-6 affixes, Magic = 1-2 ``` ### Pattern 5 — Resurrected toggle (legacy ↔ modern render) ```cpp // D2R retains original game logic, swaps render layer if (settings.legacyRender) { Render2DSprites(scene); // original DirectDraw path } else { Render3DRemastered(scene); // Vulkan/D3D12, PBR materials } ``` ### Pattern 6 — Open Battle.net character (insecure, historical) ``` // "Open" chars stored client-side → trivial to dupe/edit. // "Closed/Realm" chars stored server-side → authoritative. // Lesson: server-authoritative state is non-negotiable for online RPGs. ``` ## 매 결정 기준 | 상황 | Approach | |---|---| | 매 modern ARPG design | D2 의 loot + skill tree 의 baseline | | 매 anti-cheat | Server-authoritative state | | 매 retention | Ladder / season reset | | 매 monetization 2026 | Cosmetics-only (D2R) vs MTX (D4) | **기본값**: 매 server-authoritative + 매 seasonal ladder. ## 🔗 Graph - 부모: [[Game-Design]] - 응용: [[Skill-Tree-Design]] - Adjacent: [[Procedural-Generation]] ## 🤖 LLM 활용 **언제**: 매 ARPG mechanic 의 design 시, 매 loot table 의 balance 분석, 매 skill synergy 의 formula 설계. **언제 X**: 매 specific D2 의 internal undocumented bug 의 정확한 reproduction (data 부족). ## ❌ 안티패턴 - **Client-authoritative state**: D2 Open Battle.net 의 mass duping 의 lesson. - **Power creep**: 매 patch 마다 의 damage inflation 의 trivialize content. - **No drop rate transparency**: 매 modern player 의 expectation 위반. - **Pay-to-win**: 매 D2 의 cosmetic-only 의 reputation 의 maintain. ## 🧪 검증 / 중복 - Verified (Blizzard official patch notes, D2 LoD wiki, Resurrected dev interviews). - 신뢰도 A-. ## 🕓 Changelog | 날짜 | 변경 | |---|---| | 2026-05-08 | Phase 1 | | 2026-05-10 | Manual cleanup — D2 design pillars + loot/skill patterns + Resurrected architecture |
